FIELD OF THE INVENTION
This invention relates generally to a zoom function system of a camera module. More particularly, the present invention relates to a zoom function system allowing three degrees of freedoms of translational adjustments of lens assemblies.
BACKGROUND OF THE INVENTION
Zoom function is now a standard function in miniature cameras. There is a constant need to improve performance of zoom function. It is advantageous to extend the zoom function technology to include more degrees of freedoms of translational adjustments of lens assemblies.
SUMMARY OF THE INVENTION
This invention discloses a zoom function system that allows three degrees of freedoms of translational adjustments of lens assemblies. The zoom function system includes an upper lens assembly, a lower lens assembly, an upper actuator, and a lower actuator. The upper and the lower actuators have stationary elements and movable elements. The upper lens assembly is attached to one of the movable elements of the upper actuator.
